About the book

Sit back and enjoy a new view

Aerial Geology is an up-in-the-sky exploration of North America’s 100 most spectacular geological formations. Crisscrossing the continent from the Aleutian Islands in Alaska to the Great Salt Lake in Utah and to the Chicxulub Crater in Mexico, Mary Caperton Morton brings you on a fantastic tour, sharing aerial and satellite photography, explanations on how each site was formed, and details on what makes each landform noteworthy. Maps and diagrams help illustrate the geological processes and clarify scientific concepts.

Fact-filled, curious, and way more fun than the geology you remember from grade school, Aerial Geology is a must-have for the insatiably curious, armchair geologists, million-mile travelers, and anyone who has stared out the window of a plane and wondered what was below.
